There is no reverb, just long release time on the AEG (Envelope). values of 55 and up will get that effect.

Also there is not really any delay, what factory sounds do you hear it? Probably talking about the synth drum patch? That's with the modulation LFO. Check out the mod matrix, it's excellent. Or do you mean the looping percussion sounds? That's just a regular loop, with, again, a long release time. Notice how it changes speed as you change the pitch!
